What are the material selection and performance indicators of the rolling mortar wall?

Rolling wall is a kind of equipment component used for crushing or grinding materials, and the determination of its material selection and performance index has an important influence on the service life, production efficiency and product quality of the equipment. The material selection and performance index of the rolling mortar wall will be introduced in detail below.

1. rolling mortar wall material selection:

1. high manganese alloy steel material: high manganese alloy steel is a kind of high hardness, high strength, wear resistance, impact resistance material. It has excellent anti-wear properties and can work under high load and high speed. High manganese alloy steel material is suitable for processing the rolling mortar wall of hard materials, such as ore, quartz stone, etc.

2. Cast iron material: Cast iron is a material with good wear resistance and impact resistance. It has high hardness and good wear resistance, and can work under high load and medium speed. Cast iron material is suitable for the processing of rolling mortar wall of hard materials, such as coal mine, iron ore and so on.

3. Cast steel material: Cast steel is a material with high hardness, wear resistance and impact resistance. It has good comprehensive mechanical properties and wear resistance, and can work under high load and high speed. Cast steel materials are suitable for rolling mortar walls that deal with various hard materials, such as cement clinker, limestone, etc.

4. High chromium cast iron material: High chromium cast iron is a material with high hardness, high wear resistance and impact resistance. It has good wear resistance and corrosion resistance, and can work under high load and high speed. High chromium cast iron material is suitable for processing the rolling wall of corrosive materials, such as chemical raw materials, sulfur, etc.

2. rolling mortar wall performance indicators:

1. Wear resistance: The wear resistance of the rolling mortar wall refers to its ability to resist wear during the running-in process. Wear resistance is one of the important performance indicators of the mill wall, which directly affects the service life and efficiency of the equipment. The measurement methods of wear resistance include hardness test, friction and wear test, etc.

2. Compressive strength: The compressive strength of the rolling mortar wall refers to its ability not to be destroyed under the action of external force. Compressive strength is one of the important performance indicators of the rolling wall, which directly affects the service life and efficiency of the equipment. Compressive strength is measured by compression test, material tensile test, etc.

3. Impact toughness: The impact toughness of the rolling mortar wall refers to its ability not to break when subjected to impact load. Impact toughness is one of the important performance indexes of rolling mortar wall, which directly affects the service life and working efficiency of the equipment. The impact toughness is measured by an impact test, a Charpy impact test, and the like.

4. Thermal stability: The thermal stability of the mill wall refers to its ability to soften, sinter or deform at high temperatures. Thermal stability is one of the important performance indicators of the mill wall, which directly affects the service life and efficiency of the equipment. The thermal stability is measured by a thermal deformation test, a differential thermal analysis test, and the like.

5. Corrosion resistance: The corrosion resistance of the rolling mortar wall means that it has good corrosion resistance in the environment such as strong acid, strong alkali and corrosive gas. Corrosion resistance is one of the important performance indicators of the mill wall, which directly affects the service life and efficiency of the equipment. The corrosion resistance is measured by a corrosion test, a solution immersion test, and the like.
